Power Purge Regeneration Modules.

Remco Engineering makes several many different configurations of regeneration modules for regenerating ion exchange columns. The two basic types are stand alone systems with pumps, tanks, valves and controls, and retrofit modules that convert existing manual systems to state-of-the-art automated ones.

Stand Alone Systems (SAS)

The stand alone systems such as the P-SIXtm regeneration module are fully integrated, skid mounted systems that regenerate individual columns automatically. These are best used on smaller, mobile columns (1-5 cu. ft.) that are moved to the regeneration module, attached with quick disconnects, regenerated, then moved back to the point of use.

The advantage of these systems is that one module will regenerate many columns per day. This allows you to segregate streams and capture different ions on different types of resin. You can even regenerate chelated and DI resins with the same system. Multiple programs can be built into one system and a control panel selector controls which regeneration cycle is run.

Automations advantage is obvious. Manual systems rely on the operator to determine how much is enough. Each cycle is different depending on how the operator feels and how much he has to do. With an automatic system, you get consistent results and consistent savings in chemical usage.

Retrofit Systems

The retrofit style systems feature an integrated valve stack and control module that are mounted by the columns which are permanently attached to the valve stack. These systems control the complete system and insure proper regeneration of the columns. These systems are available for chelated resin system and DI simplex and duplex DI systems.

Our state of the art retrofit systems are designed for shops that have large existing columns that were either installed as a manual system or as an automatic system without microprocessor control. Taking the operator out of the loop makes regeneration a snap. Just push the button and go to lunch. The system automatically regenerates the column(s) and then goes back on line. When not regenerating, the system monitors pH and level in your feed tank, controls the pumps, media filter, and many other functions. These are all built into the existing program.

Power Purge(tm) regeneration is a unique feature with Remco Engineering's systems. We air purge the columns between cycles to increase the contact efficiency of each portion of the regeneration cycle. We do not try to "push" water out of the column with regenerant and "push" regenerant out with water. This results in huge volumes of regenerant being created. By air purging the columns, the regenerant stays concentrated and can be easy isolated to a small volume.

The diverter valve assembly -
We use modular construction techniques as much as we can to insure that we can build and sell our systems at a reasonable cost. Our diverter valve (valve stack) assembly is a good illustration of this philosophy. All but one of the valves to control the flow through the system are assembled in one unit that you mount near the columns and control panel. This complete valve stack mounts on three short pieces of unistrut. The valves are air operated so it takes little time to hook up the air lines and it is easy to check and see if they are operational.

The Control System -
Our systems uses a microprocessor to control the valves and interlocks. The control system is mounted in a Nema 4x fiberglass enclosure. We feature all air operated valves controlled by manifolded solenoid valves mounted in the main control panel. The main control panel also houses the level control board, circuit breakers, power latching relay, and all motor controllers. Our system features fully automatic and manual control of the regeneration cycle. Optional systems can fully automate the process where an operator is called if needed.

Regeneration -
Regeneration is initiated with one button as is backwashing the media filter. Once the regenerant tanks are full, select either backwash column A or column B with the front pushbutton and then let the system work. Three to four hours later, depending on the system capacity, the system automatically returns to the correct state. One column or column pair is always on line during regeneration. No further operator intervention is required.
